academic snapshot

I have worked pretty much non-stop from 9am to 7pm, and 9pm to 11pm. There was some reading on the bus (almost finished Wolves of the Calla, say thankya), and a lunch break, but otherwise...yeah.

I am going to put the bedding back on my (dry! hurrah!) bed. And sleep.

But I am making this post first, for anyone who wants to know just what kind of things are eating my brains during a normal uni day.



(I am just grabbing random paragraphs from whatever notes I have uppermost in my lecture pad)

Genes: Replication and Expression

When the viral DNA is being made, AZT will be incorporated by the reverse transcriptase because it has a 5' end - but as it has no 3' end, transcription of HIV will then cease. AZT must first become phosphorylated by the cell's own machinery so that it resembles a nucleotide enough to be successfully incorporated. Drug resistance will occur if the viral reverse transcriptase can become more selective as a result of mutations.


Biological Bases of Behaviour

The posterior central artery supplies the 'back and bottom' of the brain, including inner structures such as the thalamus & amygdala, the occipital and occipitotemporal lobes. Arterial blockage can thus lead to visual deficits - if lateral damage, will lose one half of visual field - prosopagnosia, esp. if oxygen is blocked to the R hemisphere - motion/colour perception, depending on areas affected. If the hippocampus is affected: short-term memory problems. If amygdala: problems in emotional processing.


Ecology of Health & Disease

3 forms of plague caused by bacteria Yersinia pestis (once called Pastuerella pestis) - bubonic, easily identified due to swelling in lymph nodes, death is due to septicaemia from bacteria in blood (NB - rarely, septicaemic plague happens before buboes develop; mortality is higher in these cases). Mild form is like flu and leaves lingering weakness. Pneumonic form only develops once bubonic is established in human population - spreads directly human-human with no need for rats/fleas - fatal without swift antibiotic treatment.

Advanced Studies Course - Transparent Motion and the Motion Aftereffect

(this is the one I have been frantically reading for, because ARGH meeting with supervisor tomorrow and I'm meant to have thoroughly acquainted myself with a ton of psychophysical theory)

Locally paired motion is important for the MAE as well as transparency - spatiotemporal relationships on the local level can account for the unidirectionality of the MAE & exceptions to this rule. MAE is determined by the vector average of the UNSTIMULATED directions - percept is the vector average of two directions if dots are paired - adaptation occurs - we 'see' coherent motion in one direction during the MAE. Both normal motion and the MAE will be transparent when surface disparities differ (MT neuron suppression assumed to be much lower when signals do not activate the same disparity 'channel'.)

Sometimes it scares me that I hadn't done a day's worth of proper bio or psych in my life until last year.

And don't worry. I only SOUND like I know what I'm talking about. Mostly.

Biological Bases of Behavior and Ecology of Health and Disease sound fascinating. :) Randomly, did you know Colorado is one of the -- four at last count, I think -- states in the US where plague is endemic?

... skimming this, all I can think is that you sound as though you know enough of what you're talking about to help Michael Stackpole a lot with his Kryptos Plague thing.

This is proof that I am too heartily immersed in Star Wars books right now.

Also Aspen scares me because Kansas lives next door to Colorado, and they keep stealing our water. ¬_¬
